l'1.'11`e Schedulc'rcferrcd to in these Lettera Patent and 'making part of thesame.

To all whom it may conce/rn:

Be it knownthat I, JOHN BRADY, of Fall River,

in the county of Bristol' and State oi' Massachusetts,

have invented a new and improved ,Machinerior Brushing Yarn; and l dohereby declare that the following is a full, clear,aud exact description` thereof, which will enable others skilled inthe art to make and use the same, reference being` had tothe Vacccm'panyiug drawingformiug vpart ot' this` specificatron.

`Figure 1- is a side chine as applied to a slashei',` thelatter being shown in dotted lines.

` Figure 2 is a crosssectionontheline '.'x of fig. 1.

Fignre is a side view fof `the device used 'for .at-

taching the' brushes to the endless chain.`

Figure lis a crossfsecticn of iig. .3.

:Figure 5 is a side view ofthe yoke used in conuection with the device shown -iu figs. 3 and 4, for attaching the brush.

' Similar letters ofA reference `indicate corresponding parts.

I propose to employ two or more brushes, A, endless chains, B, and rollers, G, in connection with the Slasher, dresser, or thread-polishing machine for` brushing and polishing -the yarn, instead of the rotary or reciproeating'brushes 'now used; the Lobject of t-his arrangement being mainly to avoid as much as pos-,v

sible the eects of the brushes as', at present arranged in` striking the'yarn when coming down-to it, and carrying it` up whenleaving it, by whichit is broken .or strained, andtibers are dctachedfrom it.

The said brushes are caused to move along the thread a'considerablc distance after-coming in contact with it, and they may be arranged at the side where they move down to it, so as to approach it gradually', thereby avoiding the sudden shocks dueto thevrotaryrbrushes, "or the reciprocating ones;

, The ends of the brushes are caused to run along supporting bars, D,.which prevent them Ifrom pressing toc :hard 011 theryarn by the sagging ot' the chains. i

For attaching the brushes and detaehing themreadil y elevation oi'nnyiulproved ma# I propose to employ thcyokes E, attached to the chain at cne`side,'fcr inserting the end of the brush, and the yokel11 ou the other, having the hinged bar 1 `l audspriug catch F2, into which yokethe bar may be forced, and from which it may be readily released by Aforcingthe spring back and releasing the bar F.

I vpropose to mount the supports G ot'` thc endless be'its and rollers on `vertically-adjustable blocks H,

`supported on suitable standards, I, or other supports -risiugup from the frame of the slasher or other machine, and. provided with screwshaft\`s, K, or other suitable means for raising or lowering them to' adjust V the brushes relatively to the yarn; also, to raise them laterally above the yarn when required.

I also propose to mount the supports of' the end,

less chains so vthat/they can be tilted to vary the pitch or. inclination with the yarn; for instance, they may be placed on pivots, L, which, being unscrewed,

will allow them to be adjust-ed, and will hold them when screwed up again. f

.Having thus described my invent-ion,

I clainl as new and desire to secnreliy Letters 1. The guiding bars D, combined with the brushes A A, traveling on endless chains B B, `for the purpose of preventing undue pressure, as described. Y

v2. The yokes E F, spring catch F2, and bar 1*", combined, as described, for readily attaching and de tachiug `the brushes.

3. The brushfcarryiug apparatus mounted on` supports having vertical adjustment, substantially as specified.

4. The said brush-carrying apparatus, arranged substantially in the manner described, for tilting, to

vary the pitch, substantially' asspecified.

The above specification of my invention signed byme this 19th dayY of J nly, 1870. l

I JOHN BRADY.
